Maybe it's enough that your T thinks it is something you deserve.

I think that T's, like many professionals, see doing reduced rate and free work as part of a professional ethic. I justify charging high hourly rates in part so I can cut them (actually, I just scale back the hours I charge for, I don't actually cut my rate, it's a pride thing) and so I have time to do pro bono work. But I think like your T, I'm in charge of deciding whose case I want to do this for. And I'm only going to make an offer to do this if I truly want to do it.
